Definitions

  • ABSTRACT Apparatus for supporting a machine on a foundation to allow for expansion of the machine including a plurality of devices, each device comprising a first plate member having a contact face having a series of parallel corrugations and a hole, a second plate member having a contact face having a series of parallel corrugations adapted to fit the corrugations on the first plate member and a hole, a layer of resilient material located between the contact faces of the two plate members and a securement member adapted to extend through the hole in the first plate member in a tight fit and adapted to extend through the hole in the second plate member in a loose fit to allow the second plate member to move relative to the first plate member in the direction of the corrugations, this securement member being a bolt having a fixing means for securing the bolt to the machine, this fixing means being spaced from the portion of the bolt extending
  • the present invention relates to an assembly for supporting a machine on a foundation.
  • any deformation occurring in the foundation is not communicated to the machine. It has been customary to support large machinery by providing a multiplicity of points of contactbetween the base of such machinery and a foundation which is regarded as having infinite rigidity compared with the supported structure. In such a system, it is usually necessary to allow for differential thermal expansion in the plane of the supporting points and this is accommodated by completely fixing one point, and permitting a single degree of freedom locally in the direction of the expansion to all the remaining points.
  • the supported structure is regarded as completely restrained in a direction normal to the plane of the supporting points.
  • the supporting foundation could be a concrete underbed as might be employed to carry stationary machinery or a fabricated assembly of steel plates and sections as used, for example, in ships.
  • the invention includes apparatus for supporting a machine on a fixed support including a plurality ofdevices, each device comprising a first plate member attached to the machine havinga contact face having a series of parallel corrugations and a second plate member which could be attached to the foundation and has a contact face having a series of parallel corrugations adapted to intercalate the corrugations on the first plate member and a layer of a deformable, particularly a resilient material is located between the contact faces of the two plate members.
  • the machine as a whole can be maintained in any desired alignment with any separately supported apparatus without inducingexcessive internal stresses through constraining the natural requirement to expand.
  • This feature is achieved by utilizing the property of the deformableor resilient material a deformable, particularly a resilient material located between the two contact faces which confers to the assembly the property of having a high degree of resistance to deformation in one direction within the plane of the contact faces and a very much lower degree of resistance to deformation in a direction within the same. plane normal to the first direction.
  • FIG. 1 shows the plan view of a typical plate on its corrugated surface being a section along the line I--I of FIG. 2 with the upper plate and membrane removed.
  • FIG. 2 shows a side view of such an assembly looking along the axis of the corrugations on to the section along the line II-II of FIG. 1;
  • FIG. 3 shows another example with compression means in the form of a bolt and is a section on the line IIlIIl of FIG. 4;
  • FIG. 4 shows a part ofa machine with a second example incorporated
  • FIG. 5 shows a detail of FIG. 4 in larger scale
  • FIG. 6 shows a machine foundation or base B with four modified devices D of rectangular shape arranged correctly in place by having their axes of minimum resistance to deformation oriented along the lines between the support locations.
  • This support system will have the property that the point on the machine determined by the intersection of the axes will remain fixed relative to the foundation while the machine, as a whole, undergoes uniform thermal expansion. If it were desired to confer this property onto some other point on the machine, the devices would be oriented so that their axes of minimum resistance to deformation all intersected at such point. 7
  • FIG. 7 shows another example where two support devices are clamped against the machine
  • FIG. 8 is an end view of FIG. 7.
  • the plates 1 and 2 shown'in FIG. 2 are semi-circular in plan, but need not be so.
  • the plates each have one corrugated surface and are assembled with their corrugations intercalated as shown and a membrane 3 of formable or resilient material is in shear to which mode of deformation it reacts with a relatively low degree of resistance to deformation.
  • the minimum possible number of points for supporting a machine-is normally 2, 3, or 4.
  • a support point requiring provision for such expansion can possibly comprise a deformable connection having a high degree of resistance to deformation along two of its principle axes and a relatively low degree of stiffness along the remaining axis.
  • FIG. 3 By causing the deformable or resiient membrane in the device to adhere to the plates it may often be employed even when separating forces are present without any further restraint in the vertical direction.
  • compression means which can be extended bolts 4 passing through holes 5 and 5a in the two plates 1 and 2 respectively as well as through holes in the machine foundation 7 or there can be an external clamping or other arrangement to hold the assembly in compression.
  • This compression means need not be bolts but must be capable of withstanding all lifting forces and must not introduce any appreciable horizontal constraint between the foundation and the machine.
  • the length of the bolt may be ten or twenty times the thickness of the assembly.
  • the bolt by bending as an elastic cantilever allows relative lateral movement between the machine and the foundation.
  • the bolt 4 is rigidly secured to an upper plate 8 slightly spaced from an upper flange 9 by a layer of deformable or resilient material and spaced from the plate 2 and lower flange 6 so that as the flanges 9 and 6 move, due to thermal expansion, relative to the foundation 11 the bolt 4 moves freely in the hole in lower flange 6 but moves rigidly with upper flange 9 and this movement is taken up by lateral elastic deformation in the long shank of the bolt between flange 6 and flange 9.
  • the upper plate 2 of the assembly is secured to the base of the machine by fitting into a recess and the lower plate 1 of the assembly is secured to the surface of the foundation by the tight fit of the bolts 4 within holes 5 in way of plate 1 only
  • the connection between the machine and the foundation is made by introducing one of these devices at each of the support points requiring a degree of horizontal flexibility oriented so that the axis of its corrugation lies along the local direction of thermal expansion for example as shown in FIG. 6.
  • the directions of thermal expansion of each support device located at the different places where the machine is supported on the foundation or other fixed support should all coincide at a common point which will be the position where the machine remains stationary relative to the foundation. This common point can be a point of contact of the machine with the foundation or a place where the machine is suspended out of contact with the foundation.
  • the membrane 3 may only have a very little resilience or flexibility.
  • the axis of the corrugations is not in the plane of FIG. 3 or FIG. 4 but the pitch of the corrugations in these figures is different due to their different inclination to the axis of the corrugations.
  • FIGS. 7, 8 there are two devices, each comprising two plates 1 and 2 spaced by a layer 3 of deformable or resilient material 3. These two devices are arranged vertically spaced from each other respectively above and below a projecting lug of a machine M.
  • the lower device rests in a plate 20 located in the base B.
  • the upper device is urged downwardly by an upper beam 21 mounted on four bolts 22 anchored to the base B and located around the outer edge of the lug of the machine.
  • a clamping member could be used.
  • tightening of nuts 23 presses plates 1 and 2 against each other.
  • Apparatus for supporting a machine on a foundation comprising a plurality of separated support devices; each said device comprising:
  • a first plate member having a contact face carrying a series of rectilinear parallel grooves and ridges
  • a second plate member having a contact face oriented parallel to said contact face of said first plate member and itself carrying a series of rectilinear parallel ridges and grooves that are adapted to intercalate said grooves and ridges on said first plate member;
  • a layer of deformable material positioned between said contact faces of said plate members.
